LOOM warms-Linn mnroeron.

Application filed February 6, 1923 Serial No. 617,318.

To all whom it may concern:

Be it lcnown that I, ADELA'RD E. RAVENELL, a citizen of the United States, residing at Norwich, in the county of NewLondon and State of Connecticut, have invented certain new and useful Improvements in Loom VVeave-Line Indicators; and I do hereby declare the following to be full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a loom weave line indicator and it generally aims to improve a device of this character and particularly the form disclosed in Letters Patent N 0. 1,409,778, issued to me on March 14, 1922.

Another object is to provide a construction adapted for more universal attachment to the various types of looms in use and one which may be fastened to the loom frame pursuant to this end as distinguished from independent support like the disclosure in said patent.

A further object is to provide a construction having a novel mounting bracket for the active mechanism.

A still further object is to provide a form having novel means to-prevent actuation of the loom while the gaging mechanism is in operative position.

One more object is to provide a novel construction of gage.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating one operative embodiment.

In said drawings Figure 1 is a perspective view illustratingthe invention as applied to a loom, the latter being shown fragmentarily;

Figure 2 is a vertical sectional view taken substantially on line 22 of Figure 1;

Figure 3 is a vertical sectional view on the line 33 of Figure 1;

Figure 4 is a horizontal sectional view on the line 4-4 of Figure 1;

Figure 5 is a cross sectional view on the line 5-5 of Figure 1;

Figure 6 is a detail perspective view of the lock collar used on the operating shaft, and

Figure 7 is a sectional view taken on the plane indicated by the line 77 of Figure 2, looking in the direction indicated by the arrow.

Referring specifically to the drawings, the frame of a loom is fragmentarily suggested at A of which the breast beam is designated B.

A justifying mechanism is provided as generally designated 10 which is adapted to be moved into the plane of the fabric as required in determining the position of the weave line in the resetting of the woven portion of the fabric after an interruption of the operation of the loom and thus to accomplish the same function as the device of my said Patent No. 1,409,77 8. This mechanism has a bracket 11 provided with an arm 12 which may be integral therewith. A gage arm 13 is pivoted as at 14 to an arm 15 of bracket 10. At the upper end, gage 13 has spaced offset blades 16 adapted to be projected upwardly between the warped thread and the cloth being woven. The lower end of gage 13 is enlarged as at 17 to constitute a weight. Said weight has a vertical elongated slot 18 into which the crank 19 of a shaft 20 loosely extends. Shaft 20 is journaled through a depending arm 21 of bracket 15 and on one side thereof has a spacing sleeve 22 mounted as shown.' Fastened to shaft 20 on the other side of arm 21 is a depending arm 23 rigid therewith. A pointer or indicator 24 is pivoted on shaft 20 and has a screw rod 25 pivoted to its lower end as at 26. Screw rod 25 passes loosely through a guide sleeve 27 pivoted at 28 on the arm 23. A nut 29 is adjustable on rod 25 so as to vary the permissible position of said indicator 24. A coil spring 30 surrounds shaft 20 and is fastened to indicator 24 and arm 23 so as to urge the indicatorto such a position as to draw the nut 29 into contact with arm 23. Indicator 24 coacts with a dial or plate 31 which is preferably provided with a normal or unit mark or indication as at 82. In normal position, the edges of the blades 16 are adapted to lightly touch with the weave line of the fabric similar to the blades 24 in the construction of my said Patent No. 1,409,778. The normal position of indicator 24, due to weight 17 is vertical. Any deviation of said indicator 24 from the vertical may be indicated to the operator upon reference to the indicator relative to indication 32. If the weave line is too far back and is out of con placement tact with the edges of the blade 16, this fact may be readily determined bya slight swinging movement of the gage arm. When the edges of the blade are in light contact with the weave line and the pointer is directed to the unit or neutral mark 32 of the dial, the weaver will know that the fabric is in proper position to resume the operation of the loom Without possibility of producing a lay mark.

The said weave line indicator or gaging means in Figure l is shown in operative position in full lines and in inoperative position in dotted lines, being movable by appropriate means from one position to the other. The attaching arm 12, by means of an elongated slot 33 therein and a set screw ommay be adjustably and extensibly connected to an arm 35 thickened or otherulscweighted as at 36.

A substantially U-shaped attaching bracket 3'! is fastened to the breast beam B as by means of screws 38 penetrating said beam and passed through an elongated slot 39 in said bracket. Said bracket 37 has a top lug or plate 40 and, a bottom lug or plate e1. Spaced vertically disposed guide rods i2 are fastened at opposite ends to said plates 40 and 4:1 and passed through. suitable conical openings 43 in the arm 35. Plate 35 is thus slidable along said arms so that it may occupy its inoperative position as suggested in dotted lines and also its operative position as shown in full lines.

- In its operative position, the device is adapted to be held against downward disby the frictional or wedging engagement of bushings, preferably conical as shown at 44 and located at the upper end of rods 42. I

An operating arm 45 is provided to lift the device from the idle to utile position and also to force said plate 35 out of fric tional engagement with the bushing 4C4 Arm 45 at its manipulating end may have a hook shaped handle 4E6. At its other end, it is pivoted to the plate 35 by a pin 47. A suitable slot at 48 is provided through bracket 37 in order to' provide clearance for manipulation of. the rod 25.

The operating handle or lever for the loom is shown at U and is rigid with an operating shaft D journaled on the frame A. It will be realized that as is usual in a loom, the operation of shaft C from the full line or idle position to the dotted line position places the necessary parts of the loom in gear and causes operation thereof. On shaft D is a lock collar 50 which may comprise'a plurality of semi-circular sections 51 fastened together as by screws at 52 and rigidly clamped to shaft D by a set screw 53' passing through one of the sections 51. A lug 5 f projects from one of the sections 51 and is adapted to coact with the hook end 55 of a detent pawl or lever 56' which is pivoted by a pin 57 to a plate 58 secured to the bracket 37. Detent 56 is relatively long so that the hook end 55 will seek engagement with the lug 54. to restrain movement of shaft D by manipulation of the lever U.

A trip member for the detent 56 is'provided as at 59 and may be a rod having one end 60 extended loosely through an opening in lever 55 and fastened as by a cotter pin or the lik. 60. Thefother end of member 59 may be a laterally offset lug 61 disposed over and in spaced relation above the plate ll in the locked position of said pawl or lever 56. indicating or gaging means 10 is in its elevated or utiie position, lever 56 and Thus when the collar 50 are engagedand thus the lever U 7' and shaft D cannot be operated. However when said mechanism 10 is in its idle positionasshown by the dotted lines, the weighted portion 36 engages the lug 61 moving it downwardly against the plate 41 and causing the trip member 59 to elevate the lever 56 'at the end 55, thereby disengaging the collar 50 and remaining out of engagement therewith so that the machine may be freely operated while the mechanism 10 is in utile position.

As merely one embodiment has been illustrated, it is to be understood that various changes in the details, combination and arrangement of the parts may be. resorted to provided the same fall within the spirit and scope of the invention.
